I don't know much, or really anything, about wrestling but I have seen a few events on telly through friends and the athleticism and choreography on display is very impressive. I re-watched that promo clip after reading your posts and I can only imagine your pain. It was when that obviously professional-looking wrestler hit him with a chair that it struck me just how bad he is at it. Working with Jim must be like having to sit at the kid's table at dinner.
I suppose you could make being bad at wrestling your whole persona maybe? Sort of like a Tommy Cooper kind of thing? He could have it so that when he does win it's through blunder, sheer size, cheating, or even magic tranny superpowers if he wanted - there'd surely be some kind of audience for that, however niche. But I can't see anyone at all wanting to go and watch just bad wrestling technique from some pressurised Yorkshire pudding batter in a bodysuit screeching about his moobs. But again, I don't know much about wrestling.
